We would like to perform the transition from libnotify1 to libnotify4.
This transition will requires sourcefull uploads as there is a
(minimal) API change.

Note that some packages might already have some #ifdefs to manage it and
thus binNMUs might be enough for them.
For Xfce though, I'm not so sure the 4.6 supports libnotify7, while 4.8
should be mostly ok.

Let's mark #619874 as a blocker for this transition then (as a reminder).
Regards,
